rlhis invention relates to that class of agricultural appliances which is utilized for the distributing or spreading of pulverized or comminuted material-:such as fertilizer' over the ground. n

The object of theinvention, generally, is to provide Vapparatus which will accomplish the above mentioned and similar operations by means of ejecting devices actuated by a stream of Water.

More speciiic objects and advantages of the invention will appear in the following description.

The invention consists in the novel construction, adaptation, and combination of parts hereinafter described and claimed.

In the accompanying drawing,-

' Figure 1 is a view partly in side elevation and partly in transverse vertical section o apparatus embodying the present invention; Fig. 2is a front elevational view of the lower portion of the apparatus illustrated in Fig. 1; and Fig. 3 is a 3-3 of Fig. 1.

represents a tank having a funnel shaped portion 6 terminating in a relatively small spout 7 disposed tank. Extending in an inclined direction forwardly and downwardly from the spout 7 is an apron 8 which serves to baffle the de- A livery of material from the tank spout and cause the material to be discharged forwardly as it is delivered by gravitation from the spout. Located below said spout and rigidly secured thereto is a pan 9 having a substantially horizontally disposed oor 10 extending between relatively diverging side walls y P Extending horizontally, or nearly so, into the rear of the pan 9 is the nozzle element 12 of a water pipe 13.

The nozzle 12 and pipe 13 are secured tothe tank as by soldering or other suitable known means such, for example, as a strap 14.

15 represents a valve for regulating the supply of water received from a service pipe (not shown) through the medium of a flexj ible tube, or hose, 16 which may be detach-v 'delivered across horizontal section on line ln said drawing the reference numeral 5 in the vertical axis of the v obstructions forthedelivery of material from y L the vtank 5. To which end I provide within at 22, l ment 23 extending horizontally'through the" 1929. serial No. 367,957.

ably connected as by means `of a union-coupling 17.130 pipe connection 13. 18 represents legs upon which the tank and associated parts are supported and 19 is a hanllle or bail secured to the upper end of the tan u i Material for distribution is supplied in a dry state into the tank 5, descending therein lby gravitation and likewise through the funnel 6 to escape from the 'spout 7 onto the apron'S.. f.

For operation, the valve 15 is opened for therdelivery of water through the nozzle 12 into and through theV pan9, the water isthus the axis of thetank discharge Vopening and lperforms two functions: first, to produce a suction at the spout 7 where- .by `thefdelivery of thematerial 4into the `pan f .is facilitated4 and, se cond, to provide inthe Vstream of water a means Adelivering the for conveying andV material in a fan-like manner horizontally to distribute material over' a large area of ground.V

" f The lweight of the apparatus smalliand of lightweight enabling it to be readily car-V ried about vand suitably directed. Y To ensure the operation of the apparatus itv is necessary to .maintain the spout l.freeof the'spout an agitator 2O consisting 'of a piece of wire whichis bent to a. U-shape, Athe arms 21 of which have their extremities coiled, as

about a transversely arranged bar elelower end vof av supporting rod 2&1 which is rotatable in and depending from the central 'ortion of a bar element 25 forming a part of the tank structure. Y z y The rod 24'is Vlocated axially of the tank' andis manually rotatable by means of a handle lbar 26 provided in the upper. end of thero'd and above the material-receiving space ofthe tank, permitting the operator using his hand to rotate or shake the rod, the agitator andthe 'bar element 23 as ,may be required to break up accumulations within the spout 7. f

Y The agitator 2() is of especial benefit in imparting astirringaction within the spout 7.

horizontal t l u ;-zo.ntal plane,

The amount of material delivered through the spout 7 is, moreover, regulated by means of a finger controlled shutter 27 movable in guide ways 2S provided upon the underside of the tank structure to close more or less the effective opening of the spout.

In operation, the abrasive action of the f'stream` of'rwaterdelivered uponzthapan floor 10 imparts a vibratory action'to the 'lower end of the tank with respect to the agitator which is hung by means-oftheirodzrom `fthe bar which is secured to the upper portion of the tank, whence a successiono'fim pulses is afforded to shake the material downwardly through the tanksspout.

The invention Ais vconvenient .to use, and is Vparticularly valuable "foruse 1in applying 'tures togardens, lawns, etc.
